computer having a moment, with vid.

well filled up with petrol, reset my computer like i always do, usual get between 35-38 mpg. but noticed when i was home my mpg was dropping, fast! the same with the distance to go meter too.

Im puzzled as its never done this before, no light on the dash or anything tho, anyone else had this issue?

Mine does it too. Modern cars tend to switch to litres per minute or something similar when idling.

It's because the computer has been reset. It works out your average MPG over distance an needs at least 0.5miles to start working its magic. After that, the more miles you've done the more stable the reading will be.

If you've only done 3miles (for example) and then sit at a set of red lights for a minute or two the average MPG will fall very fast. This value is also used to work out the predicted range also which in turn will also react as its base sums alter.

if you want to know exactly how much the engine is using, enter the diagnostic mode by holding down the computer button and starting the car at the same time.
